Stack Implementation in C++make code for an application that uses the StackX class to create a stack.includes a brief main() code to test this class.
Stack: Stacks are a type of container with LIFO (Last In First Out) type of working, where a new element is added at one end and (top) an element is removed from that end only. Your Stack should not be of the fixed sized. It should be able to grow itself. bool empty() : Returns whether the Stack is empty or not. Time Complexity should be: O(1) bool full() : Returns whether the Stack is full or not. Time Complexity should be: O(1)int size() : Returns the current size of the Stack. Time Complexity should be: O(1)Type top () : Returns the last element of the Stack. Time Complexity should be: O(1) void push(Type) : Adds the element of type Type at the top of the stack. Time Complexity should be: O(1) Type pop() : Deletes the top most element of the stack and returns it. Time Complexity should be: O(1) Write non-parameterized constructor for the above class. Write Copy constructor for the above class. Write Destructor for the above class. Now write a global function show stack which…

Language/Type: C++ binary trees pointers recursion Write a function named hasPath that interacts with a tree of BinaryTreeNode structures representing an unordered binary tree. The function accepts three parameters: a pointer to the root of the tree, and two integers start and end, and returns true if a path can be found in the tree from start down to end. In other words, both start and end must be element data values that are found in the tree, and end must be below start, in one of start's subtrees; otherwise the function returns false. If start and end are the same, you are simply checking whether a single node exists in the tree with that data value. If the tree is empty, your function should return false. For example, suppose a BinaryTreeNode pointer named tree points to the root of a tree storing the following elements. The table below shows the results of several various calls to your function: 67 88 52 1 21 16 99 45 Call Result Reason hasPath(tree, 67, 99) true path exists…
